BRAKE-HANGER MECHANISM.

Specification of Letters Patent.

Application filed June 27, 1918. Serial No. 242,134.

To all whom it may concern:

' Be it. known that I, Enro W. PALM ms'r,

a citizen of the United States, residing at Chicago, in the countygof Cook and State of Illinois, have invented certain new and useful Improvements in Brake-Hanger Mechanism, of which the following is a specification.

This invention relates to brake hanger mechanism.

The object of this invention is to provide a simple, inexpensive and durable brake hanger mechanism wherein a brake hanger.

may be readily applied, locked in operative position, and readily removed from its 00- Fig. 2 is a sectional View taken through.

I the truck side frame and showing the hanger the associated wheel for th purpose of overapplied tothe support; and,

Fig. 3 is a fragmentary plan view of the arrangement shown in Fig. 2 and showing the manner in which th hanger is applied to and withdrawn from its support.

Thetruck side frame .10 is provided with a laterally extending bracket 11, to which a brake hanger 12 is connected, the lower end of the brake hanger being connected to a brake head 13 carryinga shoe 14 for cooperating with an associated truck wheel 15. The outer end of the bracket or support 11 is provided with a pair of jaws 16 and 17 having a receiving space 18 therebetween for the reception of the upper portion of'the hanger 12, said jaws l6 and 17 and the space 18 being slightly inclined upwardly toward coming any tendency the upper endof the hanger may have in moving toward the wheel, it being appreciated, of course, that the weight of the beam, brake heads and shoes is suflicient. to hold the upper end of the'hanger 12 in its lowermost 13031171011111 the opening 18 between the jaws 16 and 17 Ther are advantages in providing a continuous looped hanger, thereby overcoming the probability of a pin coming loose in the type of hanger which requires a pm for closing the ends of the hanger. Probably the most diiiicult problem in connection with closed link hangers, such as shown in the drawings, is the-application of the hanger to its support and the withdrawal of the hanger therefrom, and at the same time retaining the hanger in its normal operating position When it is so placed.

To meet this problem I have provided the lower jaw 17 of the hanger bracket with a hooked-projection 19 behind which one vertlcal leg of the hanger is placed when applying the hanger to its support. The

hanger is'then given a movement about the Patented Dec. 23, 1919.

vertical axis of one of the vertical legs, as

shown in Fig. 3 of the drawings, the upper portion of the hanger passing into the receiving space-18. After the hanger is appliedin this manner the lower end thereof is set in place in the brake head, it bein understood that the brake shoe is remove when the hanger is ap lied tothe'head, the brake shoe thereafter eing applied to the head, causlng the hanger to be locked to the head. With the hanger in the position given a vertical swinging movement, or a movement about one of its vertical legs as an axis, partly as a result of the hanger connection with the brake head. 'Underthese conditions it is impossible for the hanger to slide through the opening 18'between the jaws 16 and 17, and,-as a matter offact, the hanger is confined or locked in the position shown in Figs. 1 and 2, thereby preventing th hanger from being disconnected from its support and preventing the brake beam, head and shoe from falling to the track and occasioning serious results. The different portions of the hanger may be any desirable size or shape, as desired.

It is my intention to cover all modifications of the arrangement shown in the figures of the drawings falling within ithe spirit and scope of the following claims.

I claim:

thereto in one position and moved into locking engagement with said support by a swinging movement on a vertical leg as an aXlS.

2. In brake mechanism, the combination Y of a support, and a brak hanger applied thereto in'one' position and moved into look ing engagement with said support by a swlnging movement of one vertical leg about another vertical leg of said hanger as an axis.

3. In brake mechanism, the combination of a support having spaced jaws with an inolined'opening therein, one of said jaws having a projection, and a hanger applied to said support by placing a vertical leg of the hanger when in a vertical position behind said projection and swinging the upper part of said hanger into the opening between said jaws.

Signed at Chicago, Illinois, this 19th day of June, 1918.
